Installation and operating instructions for the PCB Piezotronics 137B23B ICP® pressure sensor, including setup, calibration, safety, and specifications.
This manual provides step‑by‑step guidance for installing and operating the 137B23B ICP® pressure sensor. It covers mechanical mounting, electrical connections, power requirements, and recommended operating practices for free‑field blast measurements.
Safety considerations, routine calibration procedures, and maintenance recommendations are also detailed, along with a full specification sheet that lists performance limits, environmental ranges, and electrical characteristics.
| Measurement Range (±5 V output) | 50 psi (345 kPa) |
|---|---|
| Sensitivity | 100 mV/psi (14.5 mV/kPa) |
| Maximum Pressure | 1,000 psi (6,895 kPa) |
| Resonant Frequency | ≥ 400 kHz |
| Operating Temperature Range | -100 °F to +275 °F (‑73 °C to +135 °C) |
Calibration should be performed annually, after exposure to extreme environmental conditions, or before any critical test.
The sensor requires a constant current of 2 to 20 mA, selectable depending on cable length and noise considerations.
The sensor can measure up to 1,000 psi (6,895 kPa).
